Bitcoin provides a decentralized and secure method for global transactions, but managing your digital assets requires a reliable solution. A Bitcoin wallet enables you to store, send, receive, and track your Bitcoin (BTC) securely.
This guide covers:
- How Bitcoin wallets function
- Types of wallets (hot vs. cold, custodial vs. non-custodial)
- Security best practices
- Choosing the right wallet for your needs
How Bitcoin Wallets Work
Bitcoin wallets interact with the blockchain using cryptographic keys:
- Public Key: Generates your wallet address (e.g.,
1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa). - Private Key: Authorizes transactions—never share this.
- Seed Phrase: A backup to restore access if your wallet is lost.
Transaction Process
- Sending BTC: Enter the recipient’s address and amount. Your wallet signs the transaction with your private key.
- Receiving BTC: Share your wallet’s receive address (generate a new one per transaction for privacy).
